T0 all whom t may concern.' Y n [Be-itknown that'we, WELLS G. RUGGLES,of Quincy, in the county kof Norfolkand State of'lwassachusetts, and.CHARLES H. LITTLE, of Melrose, in the county of Middlesex and saidState, citizensof the United lStates, haveV invented a new and usefulImprovement in Beaters for Liquids, of which the following is aspecification.

Ourv invention relates to "apparatus for beating eggs, cream or the likewithmaximum etliciency and which may be used with aspecially-constructed receptacle or other wise as desired.k

It consists in a new and useful improve-r ment in an arrangement ofelements whereby while in use the liquid acted upon .is driven inseveral directions andv` is" so agitated as to become thoroughly brokenupf and aerated in a very short time. While egg beaters and the likearey very welll known, it is believed. that because of the peculiarconstruction of our beater and it-selements, much more tho-rough mixingand aeration of thefliquid can be'seeured'iny a given :time than withany other beater known. A :ffl In the drawings which -illustrate thepreferred lembodiment of our invention- Figure 1 is a vertical sectionof the improved beating apparatus and its receptacle. Fig. 2 is anelevation showing the beat-V ing mechanismalone. f f

Fig. 3 is a vertical section of the mechanism operating thel agitator orbeater, and Fig. 4 is a sectional plan on the line 4 4 10 is acontainerwhich is preferably used with our beater and which preferably has a rimor bead '100 at its top edge.

16 is a plate. which forms a cover for the container 10 and also alsupport for the actuating mechanism by which the beating apparatus isoperated. This actuating mechanism comprisesV an upright 29 which ismade of sheet metal and provided with strengthening ribs 291 strucktherefrom. This upright has mounted near its upper end a stud on Vwhichturns a gear 1 5 having a handle 34 with which to rotate it. From thisupright 29 is struck a lug 28 at right angles thereto and which servesas a journal for a vertical shaft. 25. Being made of sheet meta-l thissupport is very light ynot adding materially to `the weight of thedevice Yand yet being yofsuficient-strength to perform its function ofsupporting-the rotary members mounted thereon. The lip 39 is of suchcharacter that it can be easily adjusted by bending should it be.necessary so todo in case ofany wear-v on the part'` of the gear ,15 orits bearing.. Asleeve 27 rests between the lug 28,and an eyelet 26 Whichpasses through the plate 16 and serves as a support and bearing for thesleeve 27. This sleeve carries a pinion 32 in mesh withl the gear 15 andthe sleeve'27' is shrunk or otherwise attached to the shaft 25 sothat'it supports the vshaft 25,'and the rotation of the lpinion 32 will.rotate the shaft 25. There is also struck outwardly and upwardly fromthe opposite sidejof the support 29 a liplike lug 39 the upward portionof which lies ff behind the gear'15 so that the .gear 15 cannot get outof mesh with the pinion 32 as it `might after much wear or hardvusage..

`Theshaft 25 carries'at its lower end an ycular platehaving a. rim 242and flat Vspokes 241 connecting the rim with the centre of the plate.-Carried by said kspokes and'v prefer- 'ably integral therewith'areagitating blades 23 and 24 .which are bent alternately .upvwardly'V anddownwardly from the said spokes, thus forming passages through theagitator. These alternately upwardly and downwardly bent'vbla-des 23 and24 all face -agitator 14 and also a seriesof cutterv blades '46.*' Theagitator is -in'the form of a cirdirection the blades 23 will force thevliquid i upward'and the blades 24 will force it downward, so that thestreams of liquid (as eggs,

`cream or other. like substances) will strike each other andintermingle. Moreover, as

the surfaces of these blades are generally operating at an acute angleto the Surface of the plate they will in their rotation tend lto causecross currents of the liquid from the center toward the periphery of theplate, sov that a more. violent agitation of the liquid will be causedthan in any beater' now known to us.

The cutter blades comprise thin vertical portions Li6 and horizontalportions 17 which are-.attached to the agitatorl lll so that thesecutter blades rotate with the agita-tor 14:. Thus the agitatoi'andVcutter blades together form a unit which is rotated by the rotation ofthe shatt 25. Y

To stiften the rotary structure and cooperate with the cutter blades weprovide a thin stationary trame which is hung troni the under side ofthe cover 16. This trame comprises substantially vertical members i8which are braced by a cross bar 56 and are bent outwardly below thecross bar and just above and parallel to the horizontal portions 4l? ofthe cutter blades and then downwardly as at 57 parallel to the verticalportions L160i the blades. The Vlower ends of these vertical portions 57are connected by a bar 50 which is bent upwardly at its middle 60 totorni supports 5l which may rest on the bottom of the container l0 orbeV used to support the agitator in an ordinary bowl il the container 10he not used. The cross vbar 56 is split at 561 (see Figs. 1 and 4) andits slotted portions are bent outwardly in opposite directions to tornia bearing tor the shaft 1t will be noted that by this construction notonly do the vertical portions 57 ot the frame assistrmaterially in thebreaking up or aeration of the liquid but the horizontal portions andthe crossbar 56 also are instrumental for the same purpose, cooperatingas they do with the horizontal portions ot the cutter blades.

As itis desirable that the plate or cover 16 shall be firmly attached tothe container -10 during the beating operation, we provide the plate 16with a lip 18 which lits over the thickened rim 100 at the top ot thecontainer and at certain portions about the circumference ot this lip weprovide depending lugs 19. We also provide the container with slots 21in its rim 100, these slots being equal in number with, and suitablyplaced to register with the lugs 19, the

.rim of the container and the lip 18 fitting each other so that theplate 16 carrying the beater mechanism may lit tightly over the top ofthe container, the lugs'19 litting into the slots 21. YWhen the lugs andslots are so placed the plate 16 and the parts which it carries may beturned in a horizontal plane so that the lugs will pass under the rim100 and hold the plate 16 in place as shown in Fig. 1.

In operation it will be noted that if the agitator is turned in thedirection ot the arrow (Fig. 4) the upbent blades 28 will strike theliquid and throw it down and the'downbent blades 24 will throw theliquid up. Moreover, the inclined forward edges of the blades will alsoinuence the course of the liquid. This will cause a thorough agitationof the liquid and will beat into it considerable air. Moreover, thecutter blades will assist in swirling the liquid about in the container,while the verticalparts of the frame being stationary will in a measureiniiuence this swirling action so that these various parts will all ofthem cooperate in beating up the liquid.

llhis beater is particularly adapted for egg beating, Vbecause ot thecooperation ot tne parts 57 and 48 which will cause a disintegration ofa viscous or stringy liquid such as the white o1 anv egg. It has beenfound by experience that eggs or cream will be whipped by this beaterin'a surprisingly short time due we believe to the combined action otthis agitator with its oppositelybent blades, the cutter blades and theframe. Moreover, owing to the simplicity ot its construction its partsmay be struck from sheet metal and put together at small eirpense. y f YIn Fig. 4 spokes 241 are shown slightly narrower narrow'ends as shownbeing where they oin the rim 2112 and the wider ends'where they join thecentral portion of the disk. As a result the line of theblade whichisbentvup at one fend than at the other, the

orfdo'wn from each spoke is not coincident with a radius ot the disk,and a blade therefore bent along this line as shown tendsnot only todrive the liquid through the passage formed by the striking out of theblade, but

to force the liquid outwardly vfrom the center i of the disk so that inits rotation Vthe liquid is constantly being drawn from the center ofthedisk to take the place of that forced outwardly from its edge. Thisaction causes a much more thoroughcirculation and beating up ot theliquid than when the blades are bent along a radial line. V

W hat we claim as our invention isz- 1. In a beater or aerator, thecombination with an agitator comprising vertical cutter blades and ahorizontal wheel having radial spokes and inclined radial cutter bladescarried by said spokes, said radial cutter blades heilig reversely bentso that they eX tend alternately above and below said spokes and allface operatively in the same direction and are thereby adapted to causeopposing upward and downward currents in the liquid being beaten andaerated, combined with means for supporting and rotating said agitator.
